Me, personally, I would meet him and see what he has to say, but under no circumstances sign or agree to anything without discussing it w/your lawyer. He's made a drastic turnaround it concerns me that you may get screwed over in this.
I would add to do this in a public place where's the people around you to protect yourself. For me, I'd rather go the phone route instead of in person because H seems so unstable and that's worrisome. With a phone call, you retain some control and can cut it short if he turns nasty. It is a choice that you'll have to be comfortable with, WR.
